Their focus should be on stellar games not VR. If the PSVR has taught us anything on the console it is VR is not ready to invest in at the moment. Sony has less than 1.5% attachment rate for their head set. The several people I know that have one haven't touched it in months. I rather Microsoft wait a year or two (or more if necessary) before trying VR on their console. Let the desktop pave the way. Everything will be Windows based so it will be a much easier transition to the Xbox console after the dust has settled. Their first priority on the Xbox at the moment is to make sure their catalog of first party Xbox games is strong, no more droughts. And to continue to make sure third party developers push the limits of the X.

VR still needs it's 'killer app' to even get the interest of the enthusiast and the price of the combined hardware needs to drop below $500 in order to hit mass market. No sign of the former, and the latter isn't happening any time soon.
